Arrange program windows next to one another in a flash(Windows XP, Vista, 7)

            You are doing online research for a paper, which you're weiting in Word. For that, the text editing and browser have to share the monitor. In old Windows versions, you have to constantly adjust both windows.

            In Windows 7, two ways lead you to the same destination. Windows that are not represented in full image mode can be accessed with the mouse on the title bar and dragged to the right or left screen border. As soon as you release the mouse key, Windows automatically adjusts the window such that it occupies half of the screen. On the other hand, if a window uses the entire screen, pull it to the upper border with the mouse pointer.
             Using the keyboard, you can achieve the same effect for an program window with the key combinations [Win] + [Left Arrow] or [Win] + [Right Arrow]. This functions even when the window is already in full image mode. To maximize an application, press [Win] + [Up Arrow]. The corresponding key combination [Win] + [Down Arrow] minimizes the window.
              In Windows XP, you can equip this function with the free tool AeroSnap, http://goo.gl/vXrI. Follow the instructions of the setup wizard. For AeroSnap to run on your PC, .NET Framework or higher must be installed. It is a requirement for practically all Windows systems. If it is not installed, you can download the Framework from www.microsoft.com.
              Start the tool via Start | All Programs | AeroSnap | AeroSnap. It appears as a small symbol in the system tray to the right on the taskbar. Right-click this symbol and select the context command ‘Options’. In the next dialog, activate the option ‘Autostart AeroSnap with Windows’ so that AeroSnap automatically becomes active from the next boot. Confirm by clicking on ‘OK’.
